    Set up databases with:
        unset TMPDIR
        mysql_install_db

    If this is your first install, automatically load on login with:
        cp #{plist_path} ~/Library/LaunchAgents/
        launchctl load -w ~/Library/LaunchAgents/#{plist_path.basename}

    If this is an upgrade and you already have the #{plist_path.basename} loaded:
        launchctl unload -w ~/Library/LaunchAgents/#{plist_path.basename}
        cp #{plist_path} ~/Library/LaunchAgents/
        launchctl load -w ~/Library/LaunchAgents/#{plist_path.basename}

    Note on upgrading:
        We overwrite any existing #{plist_path.basename} in ~/Library/LaunchAgents
        if we are upgrading because previous versions of this brew created the
        plist with a version specific program argument.

    Or start manually with:
        mysql.server start
    EOS
